Description

TECHNICAL FIELD [0001] The present invention relates to a pest-insensitive LED lamp and a mosquito repellent prevention illumination device for improving the environment for housing a pest,

The present invention relates to a insect-repellent LED lamp which irradiates an optimal light avoiding pests to improve the insect repellent effect, and uniformly illuminates the insect-repellent LED lamp with illumination capable of effectively exterminating the insect's mosquito The present invention relates to a mosquito repelling prevention illumination device for improving the environment of a housing culture improving a housing culture environment.

Pests react sensitively to light, and in particular, it is clear that the wavelength of light is favorable.

Techniques for eliminating pests using such pest characteristics have been introduced.

Such a technique can be classified into a method of eliminating the light irradiated with the insect and a method of eliminating the light irradiated with the wavelength of the insect, but there is a limit of the insect attracting effect, It is effective to prevent the insect pests by the light of the excrement wave wavelength.

However, since there is a burden on the power cost due to the illumination, it is preferable to use an LED (LED) having a small power consumption.

However, even if the LED is designed and manufactured to illuminate the insect evasion wavelength as the dominant wavelength, due to technological limitations, light other than the insect evasion wavelength is also emitted. When constructing the lamp using such an LED, In addition, the wavelength at which the intensity of light is largest appears different from the dominant wavelength, so that the insect repelling effect can not be sufficiently exerted compared to the speed of light (or power, light intensity) emitted from the lamp.

On the other hand, there is a continuing demand for improving the environment for housing breeding.

Barns are facilities for raising livestock such as cattle, pigs, horses, and goats. Such housing has been used for various purposes such as ventilation fan, temperature / humidity controller, etc. for the purpose of improving the living environment of livestock.

In recent years, there has been a tendency for livestock farming to become larger or more industrialized, and it is demanding an improved housing environment for livestock as well as livestock.

As part of the improvement of the environment for housing the poultry, efforts have been made to more effectively prevent insects from housing with environments where pests are likely to gather.

However, it is not yet a one-time anti-vandalism, but it can be constantly prevented, low-cost and easy to install, and has not reached the technology to effectively prevent the virus.

First, although the term is used in the optical field, the terms are clearly separated for the understanding of the present invention.

The full width half maximum (FWHM) is used as the half width in the spectral distribution and the half width in the light distribution. In the present invention, the spectral half width and the light distribution half width are used separately.

The full width half maximum (FWHM) means a wavelength width corresponding to 1/2 of the peak value in the spectral distribution curve. Specifically, it means a wavelength width having a maximum value of 1/2 wavelength in the rising section and a maximum value of 1/2 wavelength in the falling section for light having a spectral distribution of a specific wavelength band.

The half-width of the light distribution half-width means an irradiation angle at a half of the maximum intensity of the central portion in the light distribution distribution represented by the reflecting mirror for condensation. According to the embodiment of the present invention, the reflector has a cup shape that gradually increases as it is away from the LED, such as hemispherical or U-shaped. Referring to a partially enlarged view of FIG. 3, And the irradiation angle connecting the open aperture rim of the reflector is referred to as a light distribution half width (?).

The dominant wavelength is the monochromatic wavelength that intersects the spectral line in the CIE standard chromaticity diagram (or color coordinate), starting from the white point (or backspot) in the chromaticity diagram and drawing a straight line through the actual chromaticity coordinates of the radiation The chromaticity diagram is defined by the wavelength of the coordinates that intersect the outline of the diagram. This dominant wavelength generally differs from the peak wavelength corresponding to the maximum intensity in the light having the predetermined wavelength width, and is generally different from the peak wavelength.

V coating is a coating that maximizes the transmittance at a particular wavelength. To this end, it applies anti-reflection coating technology as well as coating with a color coating compound that selectively transmits light of a specific wavelength. In order to diversify the specific wavelength, various kinds of color coating compounds to be used for coating are known and are actually used. On the other hand, the transmittance for each wavelength decreases as the distance from a specific wavelength increases.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 to 3, the insect-resistant ventilation lamp 100 according to the embodiment of the present invention includes a pest-insensitive LED lamp 100 having only a narrow-band wavelength component centered on the dominant wavelength, Thereby maximizing the pest control effect.

Even if the LED 141 is fabricated to emit light of the main wavelength belonging to the insect-evasion wavelength band, it is difficult to cause the light of a narrow wavelength band to be diverted due to the manufacturing technology limit to date, The off-light is also relatively small in intensity, but its intensity is hard to ignore.

In order to overcome this limitation, the present invention overcomes the limitations of the present invention in that light emitted from an LED 141, which is manufactured to emit light having a main wavelength of a pest-bending wavelength band, Let it be investigated to appear.

Furthermore, referring to the data on the favorable relationship of wavelengths to which mosquitoes react as a kind of insect pests ("Mosquito Discharging Effectiveness Measuring Device and Mosquito Type Detection of Mosquito", Hyun Joong Kim, Graduate School of Daejeon University, May 2015) It is preferable to design and manufacture the lamp so as to emit light with the wavelength that gives the optimum effect among the band of the insect-evasive wavelength as the dominant wavelength, since the wavelength that exhibits the optimal mosquito repelling effect differs slightly depending on species or mosquito habitat environment.

The pest-resistant LED lamp 100 for this purpose includes a reflector 142 that is formed so that the light of the LED 141 manufactured to emit light of the dominant wavelength belonging to the insect-evasive wavelength band is gradually widened away from the LED 141 In order to reduce the difference between the dominant wavelength and the peak wavelength by narrowing the spectral half width and reduce the fluctuation of the dominant wavelength and the peak wavelength according to the output change of the LED 141 and to maximize the transmittance of the dominant wavelength, And the main wavelength component of the LED 141 is strongly irradiated. Thus, the pest avoidance effect is improved. Further, the body 110 has a body 110 that stably maintains the main wavelength light by improving the heat radiation effect by the structural features of the internal space.

Specifically, the insect-evading LED lamp 100 includes a double-pipe-shaped body 110 having a rigid and effective heat dissipation structure, an LED substrate 130 installed inside a lower opening side of the body 110, A driver 150 that is accommodated in the inner tube 112 of the body 110 and is electrically connected to the LED substrate 130 to light the LED 141 of the LED package 140; And a V-coated light diffusion globe 120 for blocking the lower opening of the body 110 and maximizing the main wavelength transmittance.

The body 110 includes an inner tube 112 and an outer tube 111 which are integrally formed with the outer tube 111 by vertically extending the heat radiating fins 112a formed on the outer surface of the inner tube 112, A lower portion of the inner tube 112 is partly removed and the upper opening is closed by the upper cap 113 in order to insert the LED substrate 130 at a predetermined depth from the bottom.

A plurality of the heat dissipation fins 112a are formed along the circumferential direction at a predetermined angle, so that the heat generated in the inner tube 112 is quickly conducted to the outer tube 111, do.

When the lower portion of the inner tube 112 is partially removed by a predetermined length, the light emitted by the reflecting mirror 142 to be described later is sufficiently removed to be directed to the light diffusion globe 120 without disturbance by the outer tube 112 Adjust the depth.

As shown in the drawing, the diameter of the LED substrate 130 is larger than the outer diameter of the inner tube 112 and the outer diameter of the inner tube 112 is larger than the outer diameter of the inner tube 112, A portion corresponding to the removal section of the inner tube 112 of the radiating fin 112a is provided with a groove 112b which is partially formed in a shape protruding from the inner circumferential surface of the outer tube 111 and formed close to the lower opening So that the light diffusion globe 120 is fixed by the groove 112b of the heat radiation fin 112a.

The inner space of the light diffusion globe 120 is communicated with the space between the outer tube 111 and the inner tube 112 to smoothly dissipate heat generated on the LED substrate 130.

The upper cap 113 includes a ventilation hole 113c formed in a portion covering an upper space between the outer tube 111 and the inner tube 112 and communicating with the outside and a driver 150 for lighting the LED 141 An insertion tube 113b protruding downward to be inserted into the inner tube 112 and a base 113a protruding to the outside of the insertion tube 113b so as to be inserted into the socket. Of course, it is preferable that the ventilation hole 113c is formed by the number of the partition spaces so that each space defined by the plurality of radiating fins 112a is ventilated by the outside air, and is made small so as not to easily infiltrate external foreign matter .

Here, the driver 150 is a well-known component that receives power from the outside through the base 113a and lights the LED 141, and is disposed in the inner tube 112 while being accommodated in the insertion tube 113b And can be electrically connected to the LED substrate 130 through the lower opening of the inner tube 112.

Thus, the heat generated by the driver 150 can be rapidly discharged to the outside air through the inner tube 112 and the outer tube 111 integrated by the heat dissipation fin 112a.

Since the LED substrate 130 is mounted on the upper surface of the heat sink 131 having a high thermal conductivity and the heat sink 131 is fixed to the lower end of the inner tube 112 in close contact with the LED substrate 130, 140 can be quickly released as soon as it is generated.

After the LED substrate 130 is fixedly attached to the lower end of the inner tube 112 and the LED substrate 130 is covered with the light diffusion globe 120, So that the LED substrate 130 and the light diffusion globe 120 can be radiated while being firmly supported.

The LED package 140 includes a reflector 142 and a transparent resin 142 that are formed to be widened as the LED 141 and the LED 141 are separated from each other and the LED 141 and the reflector 142 are embedded in the LED package 140 And a plurality of molds 143 are mounted on the bottom surface of the disk-shaped LED substrate 130 so as to be circularly arranged.

Here, the surface of the mold 143 has a spherical surface centered on the LED 141, thereby minimizing the dispersion of light due to refraction.

The LED package 140 is mounted on the disk-shaped LED substrate 130 one by one at a radially equidistant position with respect to the bottom center of the disk-shaped LED substrate 130. In this embodiment,

The LED package 140 having the above structure and mounted on the LED substrate 130 irradiates the light of the LED 141 having the specific wavelength belonging to the insect-evasive wavelength band as the dominant wavelength toward the light diffusion globe 120 So that the spectroscopic half-width of the irradiated light is narrowed by the reflecting mirror 142 so that the main wavelength is irradiated with the light appearing strongly.

The insect pests tend to avoid light having a wavelength of 530-630 nm. The applicant of the present invention tested the mosquito and found that the light of 580-620 nm wavelength was avoided and the repellent effect It was also found that the wavelength was different depending on the mosquito species and mosquito habitat environment.

However, even if the LED 141 is intended to emit only light of a wavelength band having at least a sufficient insect repellent effect by using a specific wavelength determined according to a pest to be avoided as a dominant wavelength in the insect-evasion wavelength band, the wavelength band appears narrow as expected However, the peak wavelength was different from the dominant wavelength, so that it was impossible to obtain a repelling effect equivalent to the intensity of the emitted light.

Furthermore, it has a relatively small amount of light in the band outside the insect evasion wavelength band, but has an intensity enough to be insensitive to the wavelength of the light, so that the repelling effect can be lowered and even the insect- .

Further, according to the spectral irradiance showing the spectral distribution according to the wavelength change with respect to the LED 141, the light distribution is different according to the wavelength. Further, since the LED 141 is covered with a mold formed of a transparent resin, variations in spectral radiance caused by the mold also occur.

When a lamp using the LED 141 is manufactured, a plurality of LEDs 141 are mounted on a lamp to obtain an expected amount of light (or a luminous flux in units of lm) or an intensity of light (output in units of W) The driver 150 is made to supply electricity of a current and a voltage corresponding to the electric current and the voltage.

As a result of experiments conducted by the inventors of the present invention, it has been found that even if the same LED 141 is used, the dominant wavelength and the peak wavelength are different according to the magnitude of the applied current and voltage, and the dominant wavelength and peak wavelength It can be confirmed that this is different. In particular, as the output increases, the dominant wavelength and the peak wavelength tends to increase, and the difference between the dominant wavelength and the peak wavelength also tends to increase.

Accordingly, in the present invention, as shown in a partial enlarged view of FIG. 3, the light-distribution half width? Of the reflecting mirror 142 is narrowed so as to obtain the spectral half width expected for the emitted light.

The light emitted from the LED package 140 may have a dominant wavelength inherent to the LED 141 or may be reflected by the LED 141 before the reflector 142 is used, The main wavelength becomes close to the original main wavelength, and the main wavelength becomes close to the peak wavelength, and the difference from the peak wavelength is reduced, so that the light intensity of the main wavelength becomes stronger. Also, even if the output (or the current and voltage) of the LED 141 is different, fluctuations of the main wavelength and the peak wavelength depending on the output can be reduced, and lamps having a uniform avoidance effect can be manufactured.

For example, the reflector 142 may have a hemispherical or U-shaped cross section, and the LED 141 may be disposed at the center of the inner bottom of the reflector 142.

The above-described spectral half-width is reduced by narrowing the light-distribution half-width? Of the reflector 142. According to the results of experiments conducted by the applicants of the present invention on a commercially available LED, it was found that when the spectral half width within 17 nm is provided, the LED is close to the dominant wavelength of the LED.

On the other hand, although the spectral half-width is reduced by narrowing the light-distribution half width? Of the reflector 142, it is necessary to have a suitable light-distribution half width in order to constitute a lamp capable of uniform illumination distribution design . That is, although the light distribution distribution can be made uniform to some extent by using the light diffusion globe 120, it is necessary to use the reflector 142 having the minimum light distribution half width? Determined according to the irradiation range of the desired lamp.

As shown in FIG. 3, the emitted light of the LED package 140 thus configured is irradiated to the light diffusion globe 120 covering the LED substrate 130.

The light diffusion globe 120 has an upper structure including a lower side structure having a hemispherical spherical surface and a fitting portion 121 inserted into a lower opening of the outer tube 111. The light diffusion globe 120 may be fixed to the body 110 by providing a projection 122 on the outer circumferential surface of the fitting portion 121 to be fitted in the groove 112b of the radiating fin 112a.

According to the embodiment of the present invention, as shown in a partially enlarged view in FIG. 3, light irradiated into the light-distribution half width? Of the reflector 142 is directly irradiated onto the lower hemispherical spherical surface of the light diffusion globe 120 without interference . To this end, the fitting portion 121 of the light diffusion globe 120 is configured to be located at a position deviated from the light distribution half width? Of the reflecting mirror 142.

However, even if the emitted light of the LED 141 is condensed by the reflecting mirror 142 having the light-emitting half-value width?, There exists light in the irradiation range out of the light-distribution half width?.

The light that is out of the light-distribution half width (.theta.) Contains a relatively large amount of wavelength components largely deviated from the dominant wavelength on the light distribution characteristics by the LED 141 and the mold 143, 121, the outer tube 111, or the radiating fins 112a, and then absorbed or reflected to arrive at the globe 120 with a weakened intensity.

The light diffusion globe 120 is V coated to maximize the main wavelength transmittance of the LED 141 and reduce the transmittance of the LED 141 as the distance from the main wavelength increases. The transmittance of a narrow wavelength band around the main wavelength is increased, and the transmittance is greatly reduced for wavelengths other than the narrow band wavelength. As a result, light having a narrow wavelength centered on the dominant wavelength is diffused and irradiated outside the light diffusion globe 120.

Here, the V coating is to form a coating film on the light diffusion globe 120 by melting a color coating compound having a hue of a dominant wavelength, and to form a coating film with a thickness such that the reflectance of the main wavelength is minimized. Thus, the transmittance of the dominant wavelength is relatively large compared to other wavelengths. Of course, the larger the difference from the dominant wavelength in the wavelength range of transmitted light, the lower the transmittance.

According to the present invention described above, the insect-repellent LED lamp according to the present invention is configured such that the light of the LED 141 having the dominant wavelength belonging to the insect-evasive wavelength band is condensed by the reflector 142, And secondarily transmits the light diffusion globe 120 that maximizes the transmittance of the dominant wavelength to irradiate the narrow band light centered on the dominant wavelength to the outside, thereby maximizing the insect evasion avoiding effect.

4 is a view for explaining another embodiment of the present invention. As shown in FIG. 4, a light blocking material 120 for blocking light emitted from the reflecting mirror 142 in an irradiation range outside the light distribution half width? And a dip switch 151 for adjusting the electric current and voltage supplied to the LED 141 by the driver 150. [

It is difficult to configure the light blocking member 123 to block all of the light in the irradiation range out of the light distribution half width? Of the light emitted from the LED 141, but the light can be minimized.

According to the embodiment of the present invention, the light blocking member 123 is formed by gradually narrowing the opening in the direction opposite to the hemispherical spherical surface in the light diffusion globe 120. It is preferable that the light blocking material 123 at this time does not fall within the light distribution half width? But has an inner inclined surface parallel to the boundary of the light distribution half width? If possible. The upper and inner inclined surfaces are preferably coated with a light absorbing material to minimize light reflection, or painted or bonded.

Accordingly, light directed toward the light blocking member 123 can be partially blocked in the light emitting direction of the LED package 140 mounted at the radial equidistant position on the disk-shaped LED substrate 130.

That is, the light emitted outside the light distribution half width (?) Can be reflected in the lamp to reach the light diffusion globe 120, and the intensity of the light can be weakened during the reflection process. However, ), It is possible to change the dominant wavelength.

By providing the light blocking material 123, the total light flux of the light to be illuminated is reduced, but the fluctuation of the main wavelength can be minimized.

The dip switch 151 is a switch connected to the driver 150 by a signal line 151a partially exposed to the outer surface of the upper cap 113. The switch 151 is connected to the driver 150 ).

The driver 150 that controls the output of the LED 141 is known, and detailed description of current or voltage control for power control is omitted.

However, in the embodiment of the present invention, as described above, when the electric current and voltage supplied to the LEDs 141 fluctuate, using the characteristics of the LEDs 141, Or to change the dominant wavelength to the DIP switch 151 so as to irradiate a wavelength having a different optimal mosquito repelling effect depending on the mosquito habitat environment as the dominant wavelength. When the dominant wavelength is adjusted as described above, the transmittance variation of each wavelength can be caused by the light diffusion globe 120 having the maximum transmittance of the main wavelength, but the control range thereof is small.

Although mosquitoes are used in pests here, they can also be applied to pests of other kinds if they can experimentally obtain differences in avoidance effects depending on the species or habitat environment.

Fig. 5 shows that the light blocking material 123 can be configured differently in the embodiment shown in Fig. 5, the light blocking member 123 is formed of a light absorbing material on the inner circumferential surface of the upper opening of the light diffusion globe 120, that is, the inner circumferential surface of the fitting portion 121.

The light blocking material 123 may be a dark color light absorbing material having a low light reflectance and a high light absorption rate, and may be coated, prepared in a band form, or attached or colored. As shown in Fig. 5, it is preferable to increase the amount of light blocking by extending the fitting portion 121 upward and widening the light blocking member 123. [

On the other hand, an umbrella-shaped barrier material may be erected upside down on the center of the LED substrate 130 in which the LED package 140 is arranged in a circular shape in order to increase the blocking amount of the light beyond the light distribution half width. In other words, the inverted triangular-pyramidal light rail can be fixed to the lower end of the support rod protruding from the bottom surface of the LED substrate 130.

Fig. 6 is a view for explaining another embodiment of the present invention, in which a cross-sectional view of the insect-proof LED lamp b and an exploded perspective view (a) of the body 110 are shown.

Referring to FIG. 6, the internal space of the inner tube 112 accommodating the driver 150 is divided into upper and lower spaces by a heat shield 114 having heat pipes 114a on upper and lower surfaces thereof, respectively. The upper space for accommodating the driver 150 and the lower space are partitioned by the heat sink 131 of the LED substrate 130 and the lower space adjacent to the heat sink 131 of the LED substrate 130. Of course, the heat shield 114 having the heat sink 114a is electrically connected to the driver 150 through the hole 114b formed by vertically passing through the center.

By providing the heat shield 114 with the heat sink 114a mounted thereon, the driver 150 does not directly receive the heat of the LED substrate 130 due to sagging downward, . ≪ / RTI > In addition, the heat in each of the compartment spaces can be effectively discharged by quickly conducting the heat to the inner tube 112 through the heat sink 114a.

Meanwhile, the insertion tube 113b of the upper cap 113 is inserted into the inner tube 112 while leaving a part of the lower space in the inner tube 112, Respectively. To this end, a protrusion protruding upward from the upper surface side heat sink of the heat shield 114 and contacting the bottom surface of the insertion tube 113b and protruding downward from the bottom surface side heat sink plate to touch the heat sink 131 of the LED substrate 130 114c).

<Specific Example>

As an embodiment of the present invention, an LED lamp for irradiating light of a wavelength at which a mosquito is avoided in a pest is described.

The LED 141 has a wavelength of 610 nm at a nominal dominant wavelength in a mosquito-excluded wavelength band of 580 to 620 nm. An LED 141 having a nominal wavelength of 610 nm is commercially available, and 610 nm can be used universally even if the environment of the mosquito species and the mosquito is changed, and there is also a compound suitable for the V coating, .

However, according to the information provided by the manufacturer regarding the main wavelength of the LED 141, for example, 610 nm is given as a nominal main wavelength of the LED, while the actual LED is used alone It can be confirmed that it is close to 610 nm when it is emitted.

After the reflector 142 is installed on the LED 141 having the main wavelength of 610 nm as described above, the mold 143 is formed of a transparent resin to constitute the LED package 140 and mounted on the LED substrate 130.

Here, the light-distribution half-value width [theta] of the reflector 142 was obtained by repeatedly experimenting with changing the half-width of the light distribution so that the spectral half-width of the light transmitted through the light diffusion globe 120 and radiated to the outside has a value within 17 nm.

The light diffusion globe 120 is made of a light diffusion polycarbonate material generally used for a globe of an LED lamp. The light-diffusing polycarbonate has a light transmittance of 85%, and thus has a reflectance of about 15%

The light diffusion globe 120 was coated with MgF ₂ as a color coating compound having a color coordinate of 610 nm as a frequency of the LED 141. At this time, the thickness of the coating film was made to be anti-reflection (AR) with a thickness minimizing the reflectance of the main wavelength. The thickness of the coating film for the anti-reflective coating was obtained by the following equation according to a known technique.

Here, n _c is AR (Antireflection) by coating a refractive index of the coating material by substituting the refractive index of MgF _2, λ is a wavelength to minimize reflectivity hayeoseo substituting the frequency artisan 610nm of the LED, it got a coating film thickness, and the thickness Lt; / RTI &gt;

A large amount of the LED lamp 100 was fabricated using the LED package 140 and the light diffusion globe 120 constructed as described above and the light emitted to the outside was analyzed to find that the main wavelength was in the range of 610 nm to 612 nm , It was confirmed that the peak wavelength was in the range of 610 nm to 613 nm and the wavelength range having the effective size was limited to 550 nm to 670 nm. And the half width is less than 17 nm.

7 is a spectrum analysis of the emission light of an LED lamp having a 17 nm spectral half width, wherein the peak wavelength is 613 nm, the average wavelength is 609 nm, the wavelength range is approximately 550 nm to 655 nm, The wavelength was 612 nm.

Of course, if the spectral fringe width is less than 17 nm, or if the thickness of the coating film for anti-reflective coating is more precisely adjusted, the main wavelength will be closer to the LED main wavelength and closer to the peak wavelength.

Referring to FIG. 8, there is shown an embodiment in which the insect-evading LED lamp 100 is composed of a lamp having a dominant wavelength for avoiding mosquitoes, and applied to a mosquito repelling prevention illumination device for improving the environment for housing animals.

Accordingly, the mosquito repelling and prevention illumination device is provided so as to illuminate the area occupied by the livestock in the housing 30 with the light of a wavelength avoided by the mosquito, by setting the mosquito-avoiding area to prevent the mosquitoes from gathering, It is important not only to illuminate the entire mosquito-free zone within a large illuminance range, but also to minimize the livestock residing in the mosquito-free zone, or to be hidden by objects placed or installed in the zone, , Thus making the mosquito repelling effect uniform across the mosquito-free zone.

For this purpose, the dominant wavelength, wavelength range, energy distribution, optical distribution, luminous flux, installation height, and installation interval of the pest-resistant LED lamp 100 are adjusted.

Specifically, a wire 10 having both ends fixed to the structure of the pest 30 so as to cross the insect-evasive zone at a height of 2.5 to 3.5 m from the bottom of the mosquito-avoiding area, an electrically connected annular socket 21, A cable 20 which is provided at intervals so as to supply electric power by wiring along the wire 10 in such a manner that the annular socket 21 is hung on the wire 10 and a cable 20 for supplying electricity to each annular socket 21 ) And supplied with electricity, light of 290 to 650 Lm having a specific wavelength as a main wavelength in the above-mentioned mosquito-excluded wavelength band is optically diffused and irradiated by the hemispherical light diffusion globe 120, whereby the mosquito- And an LED lamp 100 illuminating the illuminance.

At least one end of the wire 10 is fixed to the housing structure using a turnbuckle 11 so that the wire 10 is fixed to the wire 10 using the turnbuckle 11 interposed between one end of the wire 10 and the housing structure. So that the tension applied to the belt 10 can be adjusted. By using the turnbuckle 11 as described above, the wire 10 can be prevented from being struck. Of course, if there is a housing structure at the place where the wire 10 passes, it may be carried over the structure using a hanger or the like.

Although not shown in the drawing, the cable 20 has a length sufficient to supply electric power through one end of the wire 10 after wiring along the wire 10, and one end of the cable 20 is connected to an electric supply line And the electric leakage is protected by the leakage wire breaker and the electric power is supplied. Of course, the cable 20 may be tied to both sides of the wire 10 along the wire 10 so as not to be struck, and eventually the distance between the annular sockets 21, Or the interval of the insect-evading LED lamp 100 is kept constant.

The earth leakage breaker may be replaced with a multi-outlet having a function of preventing electrical leakage, and a plug may be provided at one end of the cable 20 so as to be electrically connected to the multi-outlet.

The wire 10 for supporting the cable 20 can be easily installed in the housing structure while tension is controlled by the turnbuckle 11 and the cable 20 is processed in the air of the insect- The cable 20 can be easily wired even in a housing where it is difficult to conduct electric wiring. An LED lamp 100 capable of applying a load to the cable 20 is inserted and connected to the annular socket 21 that spans the wire 10 so that a load due to the weight of the LED lamp 100 is transmitted to the cable 20 So that the tension applied to the cable 20 can be reduced so that the cable 20 can be wired without being disconnected.

Before the wire 10 is fabricated, each annular socket 21 of the cable 20 is wired over the wire 10 and the LED lamp 100 is connected to each annular socket 21 The wire 10 may be machined. In this case, the installation work becomes easier. To this end, it is preferable that the annular socket 21 has a ring shape extending over the wire 10 so as to allow the wire 10 to pass therethrough, so that the wire 10 can be gripped.

At this time, the height h of the LED lamp 100 is 2.5 to 3.5 m, and the distance d and w is 5 to 7 m.

If the height h is less than 2.5 m, it is difficult to uniformly illuminate the whole of the mosquito avoiding area, and furthermore, it is not directly illuminated to the field of view of the livestock. And, if it is higher than 3.5m, many shady places can occur, and mosquitoes can gather in the shady place.

The intervals d and w are selected within the range of 5 to 7 m so as to illuminate the entire mosquito-avoided area with uniform illumination while minimizing the number of LED lamps 100 installed. That is, when the distance is smaller than 5 m, the number of LED lamps 100 to be installed is excessively increased. When the distance is larger than 7 m, it is difficult to obtain a uniform illuminance even if illuminated through the spherical spherical surface of the light diffusion globe 120.

The LED lamp 100 has a main wavelength of 610 nm as described in the specific embodiment of the present invention. Although the LED lamp 100 varies depending on the environment of the housing 30 and depends on the back height h and the equal intervals d and w, It is assumed that it has a light flux which can be transmitted.

It is known that a mosquito can obtain a repelling effect at an illuminance of 0.1 Lx to 10 Lx, but since the illuminance for exhibiting an optimal repelling effect is 1 Lx to 3 Lx, this range is adopted.

Considering the height, spacing, and general housing environment of the LED lamp 100 having the reflector, V coating and hemispherical diffusion illumination surface, the applicant of the present invention calculated the illuminance and installed it, and as a result, the luminous flux was 290 to 640 Lm It was appropriate to select within the range.
